Definitions

  • the present disclosure relates generally to inflatable airbag cushions for motor vehicles. More specifically, various embodiments of the present disclosure relate to inflators adapted for use in inflatable airbag systems for motor vehicles.
  • Modem motor vehicles typically employ various occupant protection systems that self-actuate from an undeployed to a deployed state without the need for intervention by the occupant.
  • Such systems often include an inflatable occupant protection system in the form of a cushion or bag, commonly referred to as an "airbag cushion,” which is now a legal requirement for many new vehicles.
  • airbag cushions are typically installed in various locations in a vehicle and may deploy into one or more locations within the vehicle between the occupant and certain parts of the vehicle interior, such as the doors, steering wheel, instrument panel, dashboard or the like, to prevent or cushion the occupant from forcibly striking such parts of the vehicle interior.
  • the airbag cushion is conventionally housed in an uninflated and folded condition to minimize space requirements.
  • an accelerometer within the vehicle measures the abnormal deceleration and triggers the expulsion of rapidly expanding gases supplied or produced by a device commonly referred to as an "inflator.”
  • the expanding gases fill the airbags, which immediately inflate in front of the driver and/or passenger to provide protection from impact against a windshield, dashboard, or other surfaces of the vehicle interior.
  • the inflator 102 is typically coupled with an airbag cushion 104 in such a manner as to enable the expanding gases to enter the airbag cushion 104 during deployment.
  • the inflator 102 In order to attach the inflator 102 to an armature 106 of a steering wheel 108, the inflator 102 conventionally includes a flange member 110.
  • the flange member 110 of the inflator 102 typically includes about four (4) holes in the flange member 110 that attach to a studded retainer ring 112, as shown.
  • the flange member 110 includes about four (4) studs (not shown) for attaching the inflator 102 to an airbag module.
  • the inflator, together with the retainer ring 112 and the airbag cushion 104 can then be attached to a housing 114, and the housing 114 can be coupled to the steering wheel armature 106.
  • the housing 114 includes a lid member 116 which can be secured about the housing 114 once the airbag cushion 104 is folded within the housing 114, or the lid member 116 can be integral with the housing 114.
  • the plurality of components used for conventional assemblies can require substantial space in a typically small area of, for example, the center portion of the steering wheel. Therefore, it may be desirable to provide assemblies that use fewer components and can reduce the space requirements of an airbag cushion assembly.
  • an inflator may include a body comprising a base member and a diffuser member coupled together.
  • the body is devoid of a lateral inflator coupling flange.
  • At least one fastener may be coupled to the base member of the body.
  • a quantity of gas generant and/or stored gas may be disposed within the body.
  • an initiator may be coupled to the base member. The initiator may be disposed at least partially within the body to be in sufficient communication with the quantity of gas generant to initiate a reaction for producing a supply of inflation gas and/or for causing the release of stored gas during deployment.
  • Additional embodiments of the present disclosure comprise inflatable airbag systems.
  • such systems may include an airbag cushion, which cushion includes an inflatable body with an opening for receiving a supply of inflation gas.
  • a flangeless inflator may be positioned at least partially within the opening of the airbag cushion.
  • the inflator includes a diffuser member coupled to a base member. Additionally, at least one fastener is coupled to the base member. The at least one fastener is coupled to an armature of a steering wheel.
  • inventions of the present disclosure comprise methods of forming a flangeless inflator adapted for use with an inflatable airbag cushion system.
  • One or more embodiments of such methods may include forming a body that is devoid of a lateral inflator coupling flange. At least one fastener is coupled to the body.
  • a quantity of gas generant (and/or stored gas) is disposed within a portion of the body, and an initiator is positioned at least partially within the body, so as to be in sufficient communication with the quantity of gas generant to initiate a reaction for producing a supply of inflation gas during deployment.
  • FIG. 2 is an isometric view of an inflator 200 according to an example of at least one embodiment of the present disclosure.
  • the inflator 200 is formed as a disk-shaped inflator and includes a base member 202 and a diffuser member 204.
  • the base member 202 and the diffuser member 204 are coupled together in a conventional manner (e.g., by a weld, adhesive, mechanical means, etc.) to form a body 206.
  • the base member 202 can comprise a dish-shaped configuration with a lateral sidewall about its lateral diameter.
  • the base member 202 may be configured to receive and be coupled with at least one initiator (e.g., initiator 304 in FIG. 3 ). That is, the base member 202 may include an aperture 212 adapted to receive and be coupled with one or more initiator assemblies that are common in the art.
  • the diffuser member 204 can also comprise a similar dish-shaped configuration with a lateral sidewall around its lateral diameter.
  • the sidewall of the diffuser member 204 can include one or more apertures 208 through which an inflation gas can exit from the inflator 200 during deployment.
  • neither the base member 202 nor the diffuser member 204 are formed with, or are coupled to a lateral inflator-coupling flange.
  • a lateral inflator-coupling flange refers to a protrusion that extends laterally from one or more portions of the lateral diameter of the body 206, and that is sized and configured to be capable of including attachment means for coupling the inflator to another component.
  • An example of such a lateral inflator-coupling flange is the flange member 110 in FIG. 1 that is adapted to include one or more apertures for receiving a fastener (e.g., a mounting stud) or one or more fasteners coupled directly thereto.
  • the inflator 200 is formed without such a flange member capable of including holes for receiving fasteners or including fasteners coupled thereto (referred to herein as flangeless).
  • At least one fastener 210 is coupled directly to the base member 202.
  • the fastener 210 shown in FIG. 2 is a mounting stud

  • the at least one fastener 210 may comprise a self-clinching fastener that is press fit through a respective hole in the base member 202.
  • the inflator 200 may be coupled directly to the armature of a steering whee1, as opposed to conventional implementations where the inflator is coupled to a housing, and the housing is then coupled to the armature of a steering wheel.
  • fewer fasteners 210 may be employed than the four fasteners used in conventional inflators.
  • some embodiments of the inflator 200 may include only a single fastener 210 coupled to the base member 202.
  • Other embodiments may include only two fasteners 210.
  • the inflator 200 may include more than two fasteners 210 coupled to the base member 202.
  • the body 206 of the inflator 200 may be sized and shaped to enclose or at least substantially enclose various components and features.
  • FIG. 3 a cross-sectional view is shown according to at least one embodiment of the inflator 200 of FIG. 2 .
  • the inflator 200 may include a quantity of gas generant 302 disposed within the body 206.
  • the gas generant 302 comprises a material adapted to generate (e.g., be converted into) a supply of inflation fluid during deployment of the inflator 200.
  • the body 206 further includes an initiator 304 coupled to the aperture 212 of the base member 202 (shown in FIG. 2 ).
  • the initiator 304 is positioned so that it is in sufficient communication with the gas generant 302 to initiate a reaction of the quantity of gas generant 302 for producing the supply of inflation gas during deployment.
  • the initiator 304 is generally adapted to initiate such a reaction of the quantity of gas generant 302 upon receipt of an electrical signal, such as may be generated by a sensor (not shown) upon the sensing of a collision.
  • a filter 306 may be provided, which filter 306 is adapted to remove debris and heat from the inflation gas as the inflation gas is flowing to the apertures 208 of the diffuser 204.
  • the filter 306 can accordingly be positioned within the body 206 of the inflator 200 between the quantity of gas generant 304 and the apertures 208 in the diffuser 204.
  • the inflator 200 may include a washer 402 positioned adjacent to the base member 202, as shown in FIG. 4 .
  • the washer 402 may comprise a metallic plate that has one or more openings 404 through which the fasteners 210 may extend and through which electrical access may be provided to an initiator.
  • the washer 402 may be adapted to aid in shielding heat produced by the inflator 200 during deployment from portions of an inflatable airbag cushion coupled to the inflator 200.
  • the inflatable airbag cushion system 500 may include a flangeless inflator 200 that is coupled to an airbag cushion 502 and to an armature 504 of a steering wheel 506.
